长江干线重点支流河口航标配布方案

长江干线重点支流河口航标配布缺乏统一配布原则和方法。采用分类研究的方法,根据河口地形及干线航道布置特点,将河口分为沿岸航道(或偏靠河口侧的河心航道)类、干线航道与支流河口间有一定距离类,确定不同类别河口航标配布所使用的航标种类,并分别根据标示支流河口位置、标示干支航道交汇点、标示干线航道与支流航道连接段航道界限与碍航物、提示支流河口信息的总体原则对不同类别的支流河口提出相应的航标配布方案,为类似工程提供参考。

Distribution schemes of navigation marks for key tributary estuaries of the Yangtze River trunk line

The distributions of navigation marks for the key tributaries of the Yangtze River trunk line are lack of uniform distribution principles and methods.We adopt the method of classification study according to the features of estuary topography and main channel layout,divide the estuaries into two types,which include coastal channel (or the main channel on the estuary side) type and the main channel and the tributary estuary have a certain distance type.We determine the types of navigation marks used for different types of river navigations,and propose the corresponding distribution schemes of navigation marks for different types of tributaries and estuaries in accordance with the general principles of marking the location of tributaries and estuaries,marking the intersection of the main and tributary channels,marking the boundary of the main channel and the tributary channel,and the obstruction of navigation,and suggesting information about tributaries and estuaries.It can provide references for the similar projects.
